IMPROVED LASTING-TACK.

Specification forming part ot' Letters Patent No. 41.584, dated February9, 1864.

To all whom it may concern.-

Be it known that I, LUTHER F. TEAYEE, a resident of Randolph, in thecounty of Norfolk and State of Massachusetts, have invented a new anduseful Improved Lasting-Tack; and I do hereby declare the same to befully described in the following specification and represented in theaccompanying drawings, of which- Figure 1 denotes a side elevation, Fig.2

an edge View, and Fig. 3 a perspective View,

of it. Fig. 4 is a perspective View of the ordinary lasting-tack, onwhich my invention is an improvement.

Lasting-tacks are used for confining the upper-leather of a shoe to alast during the process of lasting such leather. As usually constructed,these tacks have cubical or prismatic heads, as shown in Fig. 4. Theform of these heads is very objectionable, forwhile connecting the upperleather to the sole of a shoe the thread used in the sewing of the twotogether is apt to catch or be caught on and by such heads of thelasting-tacks. In order to prevent this from taking place I make thetack with its head curved on its upper sur- -face and flat on twoopposite sides, substantially as shown in Figs. l, 2, and 3, in which adenotes the head, and b the body or shank of the tack.

By making the tack-head with two dat and parallel or nearly parallelsides, it can readily be seized by pinchers, in order to draw itfrom alast.

By having the head curved, as shown in Fig. 1, a thread-loop will easilyslip from the head, and not catch or hold on it during the process ofsewing the leather held by the tack.

I claim as my invention- Theimproved lasting-tack as made with its headround or curved, and having flat sides arranged with respect to thesame, in manner substantially as described.
